STRIKE-PLATE FOR LOCKS.

SPECIFICATION forming pa 0 Letters P tnt No. 749,818, dated. January 19, 1904.

Application filed April 30, 1903. Serial NO- 154,995. (N0 IIIOdQL) To all whom. it may concern:

Be it known that I, CHARLEs HAMEL, a citizen .of the United States, residing in Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in-Adjustable Striking-Plates for Locks and Latches, of which the following is a specification.

This invention relates to adjustable striking-plates for looks and latches.

The principal object of this invention is to cover the wood of the jamb above and below the movable parts of the device within the depression or shallow mortise which commonly receives the striking-plate.

Other objects of this invention are simplicity of construction and convenience of use.

The parts of the striking-plate herein described may be formed out of sheet metal by dies at slight expense, and said plate may be secured to the jamb by two wood-screws, such as are commonly employed to hold a non-adjustable striking-plate in place.

In the accompanying drawings, Figures 1 to 4 are'oblique'views, Fig. 1 representing a striking-plate proper; Fig. 2, the complete device attached to a jamb or door-casing; Fig. 3, the main base-plate, and Fig. 4 the auxiliary base-plate. Fig. 5 is a Vertical longitudinal central section of an end. portion of the device and of the jamb or door-frame to which it is attached.

A is the jamb or door casing.

B is the striking-plate proper, provided with the usual strike 5, which projects beyond the jamb to receive the blow of the bolt of a knoblatch. The plate B in form is substantially like the ordinary non-adjustable striking and of an inside length sufficient to allow the full longitudinal movement therein of the plate B, the movement of course being limited by the length of the slot 6 6 The base-plate C is provided with a bolt-receiving opening 0 of a width as great as either of the openings b b and of sufficient length to allow the bolts to pass through said base-plate after havingpassed through the striking-plate whatever be the position of the. latter. The baseplate is provided with round holes 0 0 through which screws may be driven into the wood of the jamb or door-casing after passing through the slots 6 b of the striking-plate. The holes 0 c are placed at the middle of the slots 6 b when the plate B is midway between its extreme positions on the base-plate. The side or rim 0 of the base-plate reaches to the outer face of the striking-plate and is intended to be flush with the surface of the jamb or doorcasing when in position; but a part of this rim 0 is cut away at 0* for a distance sufficient to allow the strike Z) to have its extreme adjustment in either direction, and in Figs. 2 and 3- said rim is shown as cut away at both sides of the base-plate to allow the striking-plate to be reversed.

Of course when the base-plate is applied to the jamb or casing the woodon the side of the striking-plate is cut away at a to permit the adjustment of the striking-plate and its strike. To cover the wood above and below the strike 6, I use the auxiliary base-plate C, (shown in Fig. 4,) which is made of sheet metal preferably and is provided with upturned ends 0, which serve as a continuation of the rim of the plate C, said plate C having prongs 0", adapted to enter the wood of the jamb or casing, as indicated by dotted lines in Fig. 2, and retained in the wood by the overlying strike 6. Obviously the auxiliary plate C may be placed on either side of the plate C.

The above-described construction enables the entire device to be secured in place and the striking-plate to be held in its place by a single pair of screws'that is, the securing means are common to the striking and the base plate.

I claim as my invention 1. The combination of the base-plate, the strikingplate adjustable thereon and having a strike, means of securing said plates to a jamb or door-casing, and an auxiliary baseplate adapted to be attached to said jamb or being discontinued for a distance to permit casing and to be retained thereon by said the adjustment of said strike.
